temperature_min_wc: Calculate minimum temperature statistics based on WorldClim

Description

This function allows to efficiently calculate minimum temperature statistics from Worldclim for polygons. For each polygon, the desired statistic/s (min, max, sum, mean, median, sd or var) is/are returned.

Usage

calc_temperature_min_wc(engine = "extract", stats = "mean")

Value

A function that returns an indicator tibble with minimum temperature statistics as variables and corresponding values as value.

Arguments

engine

The preferred processing functions from either one of "zonal", "extract" or "exactextract" as character.

stats

Function to be applied to compute statistics for polygons either single or multiple inputs as character. Supported statistics are: "mean", "median", "sd", "min", "max", "sum" "var".

Details

The required resources for this indicator are:

• minimum temperature layer from worldclim_min_temperature

# \dontshow{
mapme.biodiversity:::.copy_resource_dir(file.path(tempdir(), "mapme-data"))

outdir <- file.path(tempdir(), "mapme-data")
